Self-Cooling Supercomputer

A Fahrenheit adsorption cooling system is supporting sustainable energy efficiency at the Leibniz Supercomputer Centre.

Data centers use a lot of electricity! On the one hand for data processing, on the other hand for cooling the processors. Energy efficiency is the top issue here. A supercomputer is in operation at the Leibniz Supercomputer Centre (LRZ) in Munich-Garching, which is cooled by a Fahrenheit adsorption chiller. That means: The heat produced by the processors is converted into cooling energy for the cooling system. This saves electricity and significantly reduces CO2 emissions.

CCHP with Adsorption: Proven Results

How can our energy supply be made efficient, climate-friendly and economically sensible? In this context, Offenburg University of Applied Sciences has investigated the use of adsorption chillers from FAHRENHEIT in the Laboratory for Energy Network Systems. The results of the extensive measurement campaign have now been published in a special edition of the engineering newspaper HLH.

This publication confirms the great potential of our machines for use in process and air-conditioning cooling: In addition to the high electrical efficiency when operating with pure waste heat, the energy network with a CHP unit as a combined heat, power and cooling system also showed convincing advantages. With grid-compatible operation, both energy efficiency was increased and operating costs were reduced.

CO2-neutral heat with geothermal energy

As of October 1st, FAHRENHEIT is a member of the “Wärmewende durch Geothermie” initiative, in English: The “heat recovery through geothermal energy” initiative. The initiative works to promote using geothermal energy, the fastest possible solution for supplying urban regions with CO2-neutral heat.

Many of FAHRENHEIT’s installations occur in combination with local or district heating networks. When they are combined with geothermal energy, it is particularly advantageous for the environment. Geothermal energy decarbonizes existing heating networks and reduces energy imports.

Two examples:

In 2015, FAHRENHEIT set up DJE Kapital AG’s head office with a highly efficient adsorption cooling system on behalf of IEP Pullach, the geothermal energy provider in Pullach. The realizable environmental benefits as well as the easily calculable cooling costs, without capital commitment or maintenance costs, were a major selling point. In 2019/2020, DJE Kapital AG expanded their headquarters and a newer version of FAHRENHEIT’s adsorption technology was selected for the new building.

In 2014, FAHRENHEIT worked with the Bavarian geothermal plant operator Geovol to install a FAHRENHEIT adsorption refrigeration plant at their new energy centre. This refrigeration plant operated with district heating of approximately 90°C. With FAHRENHEIT’s adsorption refrigeration technology, Geovol reduced electrical energy consumption by around 31 MWh/y and, according to projections, also reduced CO2 emissions by around 12 tonnes per year.

Our commitment to CHP – FAHRENHEIT joins the B.KWK

We are excited to announce that we are joining the Bundesverband Kraft-Wärme-Kopplung e.V (B.KWK), in English: The Federal Association for Combined Heat and Power Generation.

The B.KWK works to protect the environment and conserve resources through the development of combined heat and power (CHP) generation in Germany. As a member of the B.KWK, FAHRENHEIT will be able to exchange information and best practices with other industry leaders. A large number of our installations are already done in combination with CHP, this collaboration will lead to continued success.

CHP, also known as cogeneration, is an energy efficient technology that generates electricity and heat at the same time. The generated heat is then used within the industrial process (e.g. for space heating or for air conditioning, using adsorption refrigeration systems) and does not go to waste. CHP significantly reduces electricity costs, relieves the load on the grid, and supports distributed energy supply systems.

For Example: In 2018, FAHRENHEIT worked with Sparkasse Passau to set up a CHP plant with their sustainable cooling systems. The compact CHP is powered by environmentally friendly gas and provides 50kW of electrical power and 85kW of thermal power. In using FAHRENHEIT’S adsorption cooling system with the CHP, Sparkasse Passau has reduced their electricity consumption by almost 60% while also making a positive contribution to the city’s climate.

How do you cool an ice-cream factory?

In summer, when the love of ice cream reaches its peak, the energy required for ice cream production rises. The air conditioning requirement is high and the solar thermal system, which is designed for the transitional period, together with the existing 50 compressors, produce heat in excess. With FAHRENHEIT adsorption technology, this available waste heat can be converted into cold in an environmentally friendly way to save energy and resources and avoid overloading the plant.

We spoke with Olaf Höhn, Managing Director of Florida Eis, a long time FAHRENHEIT customer, about his experiences with our adsorption technology. They use our adsorption chillers, among other technologies, to make their ice cream production process sustainable and CO2 neutral. For more than seven years, Florida Ice has been air-conditioning the production room with our energy-saving technology, saving at least four tons of CO2 emissions per year.

Many thanks to Olaf Höhn and the whole team of Florida Eis for this interview!
